I was thinking of an object that makes you write a horrible article about it.

Like for instance copy and paste from other articles and then just delete the numbers in the article so that it would look like the SCP doesn't have a number (SCP-XXXX ->SCP-) (although it would be hard to understand what that means).

Maybe add a lot of images that don't make sense and are weirdly placed.

Then put the parts of an article in reverse order (logs first, then description, then containment and then class and item#).

Then at the end add "HELP ME, I CAN'T STOP!" or something like that. Maybe make it look disturbing (like adding spaces or messing it up with other letters) or even put it throughout the article.

After the article there could be links to places that don't really exist ("www.eouhgSDGQEHGBGSVEAWRGVSBEGERHdgbsedvfxdsgasghae.ertwbeq/ytvbwetgdaswgbr.ybrew" or something like that) and/or to places that the object has infected.

I have no clue how you could possibly execute this without making it look absolutely fucking terrible as an SCP (which is the look you're going for, but still). Plus, even impossible execution aside, the core idea isn't all that clever. Joke SCPs have to be more than regular SCPs that wouldn't make it otherwise.

I think this would be a really advanced concept that even seasoned SCP writers would struggle to pull off. A rule of design (and various other creative processes) is that you need to know the rules well enough before you can break them properly. If you are still perfecting how to write a good SCP article, than it will be a lot harder to write one that is suppose to be bad without just being bad.

I know there is an article similar in the J's. I think it's SCP-1337-J which is corrupting its own file and turning pieces of it to gibberish. It also seems to mash in the idea of (and i can't remember which one it is) the chess box that dealt with the disappearance of two russian girls. Now THAT file creeped me right the hell out!

So this damn article slowly corrupts as you go through the logs, and finnaly tells you, yes, YOU (by your username) that it can see you, then displays the image of the two girls in a disturbingly distorted manner! This was… immersing and terrifying when I saw it, because my heart jumped before my mind made sense of what was happening

It was down right freaky to say the least. And that form of brilliant execution has been somewhat taken. This will make a perfect execution hard, and you might need more immersion than the article itself. Try working on what you could do with that link it provides. Are you going for weird, disturbing, creepy, frightening or just something out of the ordinary? Don't try too hard to make it everything. But personally, I see a potential for a good article. Frankly maybe even a good scare like the Russian chess box. I'm a newbie, but in my honest opinion, your golden nugget lies in that link and what you do with it, and how immersed I get in the article.
